CLARENCE L. WELLS, OF QUINCY, ILLINOIS,ASSIGNOR OEONEHALF TO RAPHAEL E.LETTON, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 351,729. dated Qctcoe:26. T886." w

INCUBATOR.

Application filed Mar. h 1886. Serial No. 194,176. (No model.)

Z2) (ZZZ whom it may concern Be it known that I, CLARENCE L. .VVELLS,

T the device." Fig. 4 is a detached sectional view showing theyeggtray,and Fig. 5 is a detail view showing the flame-reducing tube.

My device is shown consisting of a lower or heating section, A, anintermediate or brooder section, B, and an upper or tray section, 0,arranged in the order specified. A drawer,

' (l, is provided in the lower section, in which- .present instance is alamp, L, as shown.

to support the heating device, which in the In the upper part of sectionA, I arrange airdrum S, having an upwardly-extended flue, .r, and adepending tube or tubes, a,theformer, :0, extending through section Band opening into section 0, and the tube or tubes a open ing intosection A. This drum has a supplemental bottom, I, slightly separatedfrom it, to form an air-space, and provided with a centralopening orinlet, 0', and outlet or outlets i. 'Theheat passes through opening 1',circulates around'thedrum proper, and passes out of outlets 17. The heatstriking said drum 'causes the air therein to rise, producing a draft,drawing the air up through tubes to into the drum, and thence throughflue xinto the tray-chamber, where it strikes against a diaphragm orplate, to, which serves as a deflector, directing the heat outward overthe eggs in the tray and causing heat to act equally on said eggs. Theair in passing through the drum is heated, as will be seen.

In the bottom of the tray-section I arrange a pan, a, to contain water,and above such pan I arrange the egg-tray, as shown, or trays, as may bedesired.

The tray Q comprises a frame, 0, having slats g, over which awire-netting, s, is passed.

This netting is depressed between the slats g, forming pockets by whichto prevent the eggs from rolling when the tray is tilted, as shown indotted lines, Fig. 4. At its center, in line with the flue w, the trayhas an upwardly-extended tubular shield, 8', preferably an extension ofnetting, s, as shown. This shield serves to prevent,the hatched chickfrom getting over the ascending column of heated air. Exit parts 3 leadout of section 0, through which the heated air discharges; V

The brooder is suitably inclosed, and may have a door, as shown in Fig.1, to permit access to the chicks. The due a, passing through thebrooder, serves to heat the same, as desired. Rods G extend from thebottom of the brooder upward through the section 0, and are secured tobrackets T, fixed to the plate 20 or the device of which such plate is apart. The plate to is preferably the bottom of a hollow chamber, W,having its bottom made rigid by battens or braces f. This chamber hasanopening controlled by a valve, (1, pivoted at a, and normally closedby a spring, 8'. A pin, 0, extends upward from the valve (1 through thecase, and may be held depressed by a button, c. Bydepressing pin 0 thevalve d may be opened to permit the escape of air from the chamber W. Alever, N, is pivoted at z, and extends over the chamber W, having itsfree end connected at b with a wire, m, which connects it at 2 with alever, F, having weight k and adjustingscrew it, and an extension whichconnects at y with a rod, e, bearing a sliding tube, K, which serves toadjust the size of the flame and thus regulate the heat. A set-screw, M,is threaded through lever N and bears on chamber \V. A thermometer, p,is provided, by which the temperature 01' the tray-section can beascertained.

In starting the incubator the valve (7. should be opened, and when thedesired degree of heat is reached such valve should be closed.

the air, gas, or vapor in the chamberWwill act on the lever N, andthrough thevarious connections and devices described regulate the flameas may be desired.

I do not in this application claim the thermostatic devices hereinshown, as such devices are covered by me in a separate appli- Then bythe action of heat the expansion of 5 ICO the heater and tray sectionsand through the cation for patent, filed Hay 1.1., 1886. No. 201,873.

I claim- 1. In an incubator, the tray-section provided with trays andwith outlets 3 belowsueh trays, combined with a heater-flue leading intosuch section, and a plate extended above the discharge end of said Ilue,substantially as set forth.

2. In an incubator, the combination of the heater-section, the brooderarranged thereon, the tray -section arranged upon the brooder, 1 and anair passage or flue extended between Serial brooder, substantially asset forth.

3. In an incubator, the combination of the l heating device, the drum S,provided with outlet-flue a: and inlettube "u, the false bottom havingopening 1' and outlet 1', and theiray section or support, substantiallyas set forth.

4. In an incubator, a tray having a central i opening, and anupwardly-extended shield surrounding the said opening, substantially assetforth.

5. An cgg-tray having a central opening and a ire-netting bottom, andhaving such bottom extended upwardly at the center, fornr ing a tubularshield surrounding the opening, substantially as set forth.

0. The combination of the heater-section, v

the tray-section, the tube or flue leading from the heater-section intothe tray-section, and a plate, '11, extended above the tray and'over thedischarge end of the due, substantially as set forth.

In testimony that; I claim the above I hereunto subseribe my name inpresence of two witnesses.
